RlBBON-FRAYING MACHINE.

SPECIFICATION forming part of Letters were No. 627,508, dated June 27, 1899.

Application filed August 4, 1898.

To all whom it may concern:

Beitknown that I, LEONIDAS E. KING, acitizen of the United States, residing at Marshalltown, in the county of Marshall and State of Iowa, have invented'a new and usefulRibborb Fraying Machine, of which the following is a specification.

In the manufacture of certain kinds of fabricssuch, for instance, as rugs-it has been customary to usea woof comprising a ribbon or strip of fabric cut from worn carpet with its edges frayed, which frayed edges form the pile of the completed rug or fabric. It is cus-' tomary also to sew ribbons or strips of fabric together and to wrap them into balls or upon ppools adapted to be carried in the shuttle of a oom.

The object of thisinvention is to provide a machine that may be operated by hand or by the application of power and which will receive the ribbons or strips of fabricthus prepared and rapidly remove the warp from the edges thereof, thus leaving the edges frayed in the manner necessary for use, as described.

A further object-is to provide a machine for this purpose which is simple, strong, and durable in construction and accurate in its operation.

My invention consists in certain details of construction, arrangement, and combination of parts as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a top or plan view of the complete machine. Fig. 2 shows a vertical longitudinal central section of Fig. 1; and Fig. 3 shows a portion of the ribbon or strip of fabric, one end of which has been passed through the machine and portions of the warp removed thereby.

Referring to the accompanying drawings, the reference-numeral is used to indicate the supporting-frame of the machine. At one end of the frame is a horizontal shaft 11, mounted to which is fixed a hand-Wheel 12, whereby the shaft is rotated. A belt-wheel is substituted for this hand-wheel when power is used. At or about the central portion of this shaftll a belt-wheel 13 is fixed.

The reference-numeral 14 is used to indicate an arm having longitudinal slots 15 therein, through which screws 16 are extended and Serial No. 687,757. (No model.)

seated in the frame 10, thus providing for a longitudinal adjustment of the said arm. In the forward end of this arm is mounted rotatably a flanged belt-wheel 17 which isin alinement with the aforesaid belt-Wheel 13. A belt or conveyer 18, having sharpened projections 19, is passed over these wheels, and obviously as the hand-wheel 12 is rotated the upper portion of this belt or conveyer will be advanced.

20 indicates a leaf-spring secured at one end by the bolt 21 to the frame 11 above the belt-wheel 13 and extending forwardly directly'above the belt or conveyer to a point near the forward belt-wheel, where it is attached to. a cross-bar 22, which in turn is mounted on the frame 10. .The function of this spring 20 is to hold the ribbon or strip of fabric closely to the beltoriconveyer.

At the rear end of the machine a platform 23 isfixed and guides 24: are mounted on the platform. The ribbon or strip of fabric is placed on this platform and is guided upon the belt or conveyer by the said guides 24.

Means are provided for guiding the ribbon or strip after-it leaves the belt or conveyer and to hold it upon the conveyer near the forward end of the machine as follows:

25 indicates a wire frame having its ends secured to the cross-bar 22 and having a loop thereof passed transversely around the belt or conveyer near the forwardbelt-wheel, and also a loop above the forwa'rd'belt-wheel.

31, they in turn being fixed to the shafts32.

These shafts are extended longitudinallymf the machine-frame and on opposite sides of thebelt or conveyer and are rotated by means of the shaft 11. At about the central portions of the shafts are fixed two disks 33, and

to each disk aknife 34 is secured, which knife is designed to coact with the straight edges 35 on the machine-frame in severing with a shear cut that portion of the warp of the ribbon or strip of material projecting beyond the belt or conveyer.

36 indicates a plate fixed to the machineframe and having a longitudinal slot 37 in its top to admit the belt or conveyer and openings 38 in its sides, through which the projections of the wheel 39, hereinafter described, may pass. This plate also forms the straight edges 35 before described. Thus as the ribbon passes over the belt or conveyer the warp on each side is cut into sections of comparatively shortlengths. A short distance in advance of these cutters two wheels 39 are fixed to the shafts and provided with a series of sharpened projections 40 on their peripheries, which extend toward the belt or conveyer far enough to engage the warp of the ribbon or strip that has been cut and draw it from the fabric, permitting the ribbon or strip to pass through with its edges frayed in the manner desirable for forming the woof-pile used in manufacturing certain kinds of rugs, &c.

In practical use an end of a ribbon or strip is admitted between the guides and over the platform at the rear of the machine until engaged by the sharpened projections of the belt or conveyer. Then it is carried forward, and as it passes the knives the warp at its edges is severed into short sections, and as it passes the wheels 36 these severed sections of the warp are removed, and the ribbon or strip with frayed edges is passed over the guide at the front of the machine.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-

1. In a machine for fraying strips of woven fabric, an endless belt or con veyer, a platform at one end of the conveyer, a guide on the platform to direct material from the platform to the endless carrier, a spring for holding the material in contact with the carrier, cutters forsevering the warp of the material, and means for directing the material as it becomes disengaged from the endless carrier, all arranged and combined as shown and described.

2. In a machine for fraying the edges of ribbons or strips of woven fabric, the combination of an endless conveyer having sharp points for engaging the fabric, an adjustable spring for keeping the fabric in contact with the said conveyer, two rotatable shafts extending parallel with said conveyer and spring and on opposite sides thereof, means for rotating the shafts, a knife on each shaft, a stationary straight edge to coact with each knife, and a wheel fixed to each shaft adjacent to the cutter and having sharpened projections therein, substantially as and for the purposes stated.

3. A machine for fraying the edges of a ribbon or strip of fabric comprising a belt or conveyer having sharpened projections, means for conveying and advancing the belt or conveyer, a leaf-spring above the belt or conveyer, to hold the ribbon or strip tightly against the belt or conveyer, a set-screw designed to limit the upward movement of said spring, a guiding device for conducting the ribbon or strip from the belt or conveyer, a device for cutting the warp at the edges of the ribbon or strip into short sections and means for removing said severed sections of warp, substantially as and for the purposes stated.
